I am making a quiz in php and I am having trouble advancing to the next question if they get the right answer. I want to stay on the same page. I tried adding 1 to the primary key of the question if a right answer is submitted but that didn't seem to work.
<?php
include('includes/config.inc.php');
?>
<?php
if ($_POST==true && array_key_exists('ans', $_POST)){
$ans = $_POST['ans'];
$question = $_POST['question'];
$sql=mysql_query("SELECT * FROM answer WHERE pk_answer = $ans;");
while($row=mysql_fetch_array($sql)){
$correct=$row['correct'];
}
echo $correct;
if ($correct == 1) {
echo "You are so cool!!!!";
} else {
$msg = "You submitted an incorrect answer. Please try again.";
$incorrect = $ans;
}
}
?>

i'm new in coding and have a problem coding on Mac.
When i do var_dump($_POST), answer is: array(0){}
Here is the code:
<?php
session_start();
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$name=strip_tags($_POST["name"]);
$age=$_POST["age"]*1;
$_SESSION["name"] = $name;
$_SESSION["age"] = $age;
}
else {
$name = $_SESSION["name"];
$age = $_SESSION["age"];
}
?>

Same time, when i press submit button it shows me:
Notice: Undefined index: name in /Applications/MAMP/htdocs/PHP_Course 2/demo/mod2/sessions/session-1.php on line 5
Notice: Undefined index: age in /Applications/MAMP/htdocs/PHP_Course 2/demo/mod2/sessions/session-1.php on line 6
Maybe someone knows what can i do.
Sincerelly
the problem with this is your session variables are not set at the beginning and you are trying to assign your $name and $age with those unassigned variables on your else block. Validate your assignments like this.
<?php
session_start();
$name = $age = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$name = strip_tags($_POST["name"]);
$age = $_POST["age"] * 1;
$_SESSION["name"] = $name;
$_SESSION["age"] = $age;
} elseif (isset($_SESSION['name']) || isset($_SESSION['age'])) {
if (isset($_SESSION['name'])) {
$name = $_SESSION['name'];
}
if (isset($_SESSION['age'])) {
$age = $_SESSION['age'];
}
}
?>

In two pages I have there problem. The first problem is before I submitted I get this alert:
(Notice: Undefined index: submit in C:\xampp\htdocs\art-legend\12\admin\add.php on line 15)
and the line 15 in this page is
(if ($_POST['submit'] && !empty($_FILES)){)
The second problem is before I put any image they put that I have an image on the top but I still don't put any image and I have this picture
And the third error is when I upload an image I can't see it and I have a screen like the last screen .

Use isset
isset — Determine if a variable is set and is not NULL
<?
if (isset($_POST['submit']) && !empty($_FILES)){
Currently I have a form that makes use of fields and check boxes. The fields and checkboxes both update the database perfectly:
<?php
function renderForm($articletitle, $articleorganization, $articledate, $articleurl, $articletags )
{
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div id="stylized" class="myform">
<form id="form" name="form" action="" method="post">
. . .
. . .
if(count($articletags) > 0)
{
$articletags_string = implode(",", $articletags);
}
if (isset($_POST['submit']))
{
$articletitle = mysql_real_escape_string(htmlspecialchars($_POST['articletitle']));
$articleorganization = mysql_real_escape_string(htmlspecialchars($_POST['articleorganization']));
$articledate = mysql_real_escape_string(htmlspecialchars($_POST['articledate']));
$articleurl = mysql_real_escape_string(htmlspecialchars($_POST['articleurl']));
$articletags = implode(',', $_POST['articletags']);
. . .
mysql_query("INSERT articles SET articletitle='$articletitle', articleorganization='$articleorganization', articledate='$articledate', articleurl='$articleurl', articletags='$articletags' ")
or die(mysql_error());
// once saved, redirect to success page
header("Location:addsuccess.html");
}
}
else
{
renderForm('','','','');
}
?>
Now, though, I'm wondering if I should have gone with a boolean checkbox instead.
The reason is that I've built an edit form as well and it follows the new entry form exactly except that values are already filled in via the MySQL DB.
So, I'm assuming that it would be considerably easier to use boolean, right?
So, instead of using an array, I should give the checkboxes different names, and on the edit.php page I can use something like:
<?php
function renderForm($id, $articletitle, $articleorganization, $articledate, $articleurl, $articletags)
{
?>

The problem with that though is that my checkboxes on the edit.php page still aren't showing the checked state.
You need to use checked="checked" in the same way as you used for value. See the solution bottom:
<input type="checkbox" <?php if(isset($_POST[articletags1])) echo 'checked="checked" ' ?>name="articletags1" value="checkbox" id="articletags_0" />
<input type="checkbox" <?php if(isset($_POST[articletags2])) echo 'checked="checked" ' ?>name="articletags2" value="checkbox 2" id="articletags_1" />
Hope this works. Updated the right code. Use ini_set('display_errors', 1); to get the error generated.

Tweak your query.
SELECT
`id`,
`question`
FROM
`question`
WHERE
`id` = '$questionnumber'
AND
`question` IS NOT NULL
AND
LENGTH(TRIM(`question`))>1

Why will the email not work as planned and is the approach correct?
I am working with this DonationScript
Your problem may be in your regexp, the * is an unknown modifier in your code example. Try this... Delete the validate email function completely. Then change
if(!validate_email($_POST['emailField']))
to
if (!filter_var($_POST['emailField'], FILTER_VALIDATE_EMAIL))
and see if that works for you.
